Edit all SillyTavern prompts and presets from a single sidebar
Diff a draft prompt against a saved baseline before applying
Snapshot lorebook entries locally and roll back changes
Switch between Prism and Monaco editors for syntax-highlighted JSON or YAML
Requires an existing SillyTavern 1.12.0+ install and a Chromium or Firefox-based browser.
This repository is an extension for SillyTavern, a desktop chat front-end used with locally hosted or remote AI chat models. The extension provides a single editor that brings together text sources which are otherwise scattered across SillyTavern's menus: prompts, preset text, lorebook entries, personas, and connection profiles. The README explains the goal as letting a user pick a source from one sidebar and edit it without hunting through different parts of the interface. The feature list describes a central source list, lorebook support that lets whole lorebooks be added and entries edited in place, a choice between two editors called Prism and Monaco, diff mode for comparing the working draft against a saved baseline or a history snapshot, local snapshot history, per-source syntax selection between Markdown, JSON, YAML, or plain text, and editor controls for word wrap, spell check, minimap, and scroll sync. Prompts can be toggled on or off and some prompt metadata can be edited. History is kept locally in the browser's IndexedDB, so it does not leave the machine. Installation is done through SillyTavern's extension installer or by cloning the repository into the SillyTavern extensions folder, then reloading SillyTavern and enabling the extension. Requirements are SillyTavern version 1.12.0 or newer and a modern Chromium or Firefox-based browser. A quick start section walks through opening the editor from the top panel, choosing visible categories under Sources, picking a source, editing, and clicking Apply to write changes back to SillyTavern. A separate flow covers using Diff to compare against the baseline and using History to commit, load, or compare snapshots. The editor notes say Prism is the default lightweight editor, Monaco is available for users who want a full code editor, indentation settings apply only to Prism, and Monaco's minimap is hidden during diff mode. Language choice is per source and is available from the status bar. The project layout includes an index.js entry shim, a manifest.json, a stylesheet, TypeScript sources for the editor shell, source manager, panels, history storage, constants, and shared types, plus a compiled dist folder that SillyTavern loads at runtime. Support channels listed are a Discord server, the official SillyTavern Discord, GitHub Issues, and a Patreon page for funding. The license is described as GNU License with the actual text in the LICENSE file.
